Abstract
[Objective] To evaluate the ecological benefits of Eucalyptus robusta plantations in Guangxi and to screen out the main technical in-dexes for promoting the development of Eucalyptus robusta.[ Method] By investigating and analyzing the present situation of Eucalyptus robusta plantation management in 8 representative areas of Guangxi, using the methods of literature search, borrowing, empirical research, quantita-tive research and qualitative research, the ecological benefits of Eucalyptus robusta plantations in Guangxi were evaluated.[ Result] The value of individual ecological services of Eucalyptus robusta plantations from small to large followed by the value of clean air, water conservation val-ue, carbon fixation and oxygen release.Ecological health value =carbon fixation and oxygen release value +water conservation value +clean air value.The average ecological health value of Eucalyptus robusta plantations in different areas of Guangxi was 165.1 thousand yuan/(hm2· a). [Conclusion]The study can provide a theoretical basis for better ecological benefits ofE uc alyptus robusta plantations in Guangxi.关键词
